  single-phase FePt nanoparticles. Nevertheless, such conditions also result in the loss of long-range arrangement and in the appearance of coalescence effects. A core–shell structure comprising of FePt and Fe3O4 is favored under mild thermal conditions during synthesis, which seems to confront the undesirable atomic diffusion. Additionally, particle isolation due to the surfactant coating leads in an

  摘要 本工作主要通过不同的电子显微镜技术和 SQUID 磁力计研究 FePt 纳米粒子的合成机制对其自排列以及一些结构和磁性能的影响。在单相 FePt 纳米粒子中，与长沸腾持续时间相关的高回流点似乎足以增加铁前体的分解产率并促进同时立方到四方 FePt 的转变。然而，这样的条件也会导致远距离排列的丧失和聚结效应的出现。由 FePt 和 Fe3O4 组成的核壳结构在合成过程中温和的热条件下是有利的，这似乎面临着不希望有的原子扩散。此外，由于表面活性剂涂层导致的粒子隔离导致 hcp 对称自组装。此外，在较低温度下工作允许不同相之间的均匀混合物产生二元复合阵列。

  The standard enthalpies of formation of some shape memory alloys have been measured by high temperature direct synthesis calorimetry at 1373 K. The following results (in kJ/mol of atoms) are reported: CoCr (-0.3 +/- 2.9); CuMn (-3.7 +/- 3.2); Cu3Sn (-10.4 +/- 3.1); Fe2Tb (-5.5 +/- 2.4); Fe2Dy (-1.6 +/- 2.9); Fe17Tb2 (-2.1 +/- 3.1); Fe17Dy2 (-5.3 +/- 1.7); FePd3 (-16.0 +/- 2.7); FePt (-23.0 +/- 1.9); FePt3 (-20.7 +/- 2.3); NiMn (-24.9 +/- 2.6); TiNi (-32.7 +/- 1.0); TiPd (-60.3 +/- 2.5). The results are compared with some earlier experimental values obtained by calorimetry and by EMF technique. They are also compared with predicted values on the basis of the semi empirical model of Miedema and co-workers and with ab initio calculations when available. We will also assess the available information regarding the structures of these alloys. (C) 2011 Elsevier B.V. All rights reserved.
• A General Strategy for Preparation of Pt 3d-Transition Metal (Co, Fe, Ni) Nanocubes

  A facile, reliable, general, and robust synthetic method for preparation of high-quality, (100)-terminated Pt3M nanocubes (M = Pt or 3d-transition metals Co, Fe, and Ni) has been developed. It was identified that addition Of W(CO)(6) is crucial for control of the nucleation process when the metallic precursors are reduced, whereas an optimized ratio of the solvent pair, oleylamine and oleic acid, is the key to enabling the lowest total surface energy on 100} facets in order to develop cubic nanocrystals in the present system. The resultant monodisperse nanocubes, in which Pt is partially substituted, are expected to exhibit unusual electrocatalytic characteristics, providing an alternative for developing high-performance electrocatalysts for use in fuel cells.

  The electronic band Structure of ordered FePt3(110) single crystal was studied by angle-resolved photoemission spectroscopy with synchrotron radiation. The energy band dispersions along the X-Gamma-X and R-M-R directions of a simple cubic Brillouin zone were Successfully observed at room temperature.,g file latter direction, band folding due to antiferromagnetic (AF) ordering was clearly observed Along the latter direction, band folding due to antiferromagnetic (AF) ordering was clearly observed below the Neel temperature (T-N2) of 100 K. Through comparison with theoretical Calculations. (1/2, 0, 0)-type AF ordering or a mixture of the (1/2, 0, 0)-type and (1/2, 1/2, 0)-type AF orderings was concluded to occur below T-N2. These magnetic orderings can be understood from the viewpoint of the nesting between the electron and hole pockets.

  The investigation of the magnetic properties of the pseudobinary Co1-xFexPt3 L1(2) ordered compounds resulting From alloying the ferromagnet CoPt3 and the frustrated antiferromagnet FePt3 is reported. dc susceptibilities and zero field cooled and field cooled magnetizations as a function of temperature and held (0-35 T) have been investigated. On the Co-rich side (x<0.6), the compounds display a long-range ferromagnetic order characterized by the occurrence of two reentrant spin-glass phases (or mixed magnetic phases) at low temperature and magnetic field starting at very low iron concentration. This ferromagnetic region is closed by a multicritical point located around x=0.55 and T=120 K. On the iron-rich side, an antiferromagnetic region with two antiferromagnetic [1/21/20] and [1/200] structures is observed for 1 greater than or equal to x>0.8. Beyond 0.8 the basic antiferromagnetic order [1/21/20] changes progressively into a spin-glass ordering and the less stable one [1/200] persists at low temperature up to Fe concentrations as high as 0.6. Although the complex behavior of the iron-rich side in the intermediate region is not totally elucidated, a tentative phase diagram is proposed and discussed comparatively with the previously determined (Fe-Mn)Pt-3 and (Co-Mn)Pt-3 phase diagrams. the occurrence of a spin-glass phase that separates the long-range ferromagnetic region from the antiferromagnetic one is specific to the (Co-Fe)Pt-3 system in agreement with theoretical models. The (Co-Fe)Pt-3 appears as the most frustrated among the three systems considered.
